Heck yeah, a yellow-on-blue flash of the past! Part of Embarcadero's "antique software" collection, which features three versions of Turbo Pascal and Turbo C++ 1.01. This brings up fond memories, as I kind of grew up with Turbo C++ 3 (the DOS version). I learned C mostly through K&R and Turbo C++'s excellent integrated online help: pressing Ctrl-F1 on an identifier brought up a the integrated help browser which also had hypertext links to related functions and overview pages for header files:

While Turbo C++ as compiler was trailing behind e.g. Watcom's in both performance and size (and we're only talking about C here, not C++), the focused simplicity of Turbo C++'s 18-years-old IDE can still serve as inspiration to present-day IDE's. As such, it's a pity that Turbo C++ 3.0 is not available directly from above antique software collection.
